Under gassed?

That's interesting. Most drill bit sets are in 1/64th increments. So .094 = 3/32 and the next step up is .109 (7/64ths). I didn't want to make that jump yet, but I feel it is still a little low since it takes a super lite buffer to run. The next step is to go to .109 and tune down the gas with the adjustable block.

This is an all new build, so I may run it as is for a while and see if I can move back up to a standard buffer after it has several hundred rounds through it.

Look for a wire gauge bit set. You should be able to get the increments needed with it.
